Low-dimensional electronic systems are at the heart of many scaling approaches currently pursuit for electronic applications. Here, we present a comparative study between an array of one-dimensional (1D) channels and its two-dimensional (2D) counterpart in terms of current drive capability. Our findings from analytical expressions derived in this article(More)
As a model system for understanding charge transfer in novel architectural designs for solar cells, double-walled carbon nanotube (DWNT)− CdSe quantum dot (QD) (QDs with average diameters of 2.3, 3.0, and 4.1 nm) heterostructures have been fabricated. The individual nanoscale building blocks were successfully attached and combined using a hole-trapping(More)
For resistive random access memory (RRAM) applications, selector devices play an important role to ensure that an individual memory element can be properly addressed through reading and writing while at the same time the information stored in the other cells of the same array does not get perturbed and power does not get wasted by undesirable leakage(More)
Based on the careful design of two-terminal devices from multi-layer transition metal dichalcogenides (TMDs) such as MoS2 and WSe2, truly vertical transport has been experimentally evaluated and theoretically analyzed. By exploring, the electric field and temperature dependence of in total 28 TMD devices of various thicknesses, a model that describes(More)
As a model system to probe ligand-dependent charge transfer in complex composite heterostructures, we fabricated double-walled carbon nanotube (DWNT)-CdSe quantum dot (QD) composites. Whereas the average diameter of the QDs probed was kept fixed at ∼4.1 nm and the nanotubes analyzed were similarly oxidatively processed, by contrast, the ligands used to(More)
